Abstract (en)
[origin: WO2006117151A1] The invention relates to a portable data carrier (1) comprising an electronic circuit (13) for storing and/or processing data and an oscillating circuit (29, 30, 31) for contactless communication and/or power transmission. The inventive portable data carrier (1) is characterized in that an actuator (30, 31) which can be influenced externally is provided for changing the resonant frequency (f<SUB>res</SUB>) of the oscillating circuit (29, 30, 31) between a first frequency range and a second frequency range.
